Hi Rick,
This is the stepper-driver-PS setup I've got...

I had made a slight change in velocity in motor tuning and then done the FRO (feed rate override) while running a program when this started. I won't repeat everything I made in a previous post but I have noticed some heat from my driver/PS enclosure as seen here...

I didn't try to deliberately stall any of the steppers before all this started but I really expected there to be more torque from this setup. I would like for my system to run fast and reliably. That being said, I'm still impressed at how you can design something in software and then have such an inexpensive machine make it so well.
I don't mind upgrading to get more torque, I just don't know if it's best (expense wise) to go with higher torque steppers or a different type of PS or if both are required.
To sum up what I would like my machine to do is to go faster (10 to 15 IPM) even if I have to have less DOC, reliably.
